WINDOW. I

Specification of Letters Patent.

Patented Feb. 18, 1908.

Application filed March 27, 1907. Serial No. 364,781.

T 0 all whom it may concern:

Be it known that I, SIDNEY U. BARR, a citizen of the United States, and a resident of the city of New York, borough of Brookly'n, in the county of Kings and State ofprovided with multiple sashes having interocking sash stiles, to give the window the appearance of a stationary muntin sash, but t e sashes are capable of being opened and closed although no mullions are used.

The invention consists of novel features and parts and combinations of the same, which will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings forming a art ofthis specification, in which similar 0 aracters of reference indicate corresponding parts in all the views.

Figure 1 is an outer face View of the improvement; Fig. 2 is an enlarged sectional plan view of the same on the line 22 of Fig-. 1; Fig. 3 is an enlarged cross section of the same on the line 3.3 of Fig. 1 Fig. 4 is a similar view of the same on the line 44 of Fig. 1; Fig. 5 is a like view of the same on the line 55 of Fig. 1, and Fig. 6 is an enlarged sectional plan of adjacent sashes, one of which is partly open.

The sashes A and A are mounted to swing in the window frame B by the use of hinges or ivots'C, C (see Fig. 2), and the adjacent stifeis-A, A of the said sashes A, A interlock with each other when the sashes are closed, so that the said interlocked stiles resemble the middle or intermediate bar of a muntin frame window. The inner face of the stile A is provided with a manually controlled bolt 1) of the extension or Cremorne type,

and adapted to engage the top cross bar B and the sill B of the frame B, to securely lock the sashes A and A in position when closed.

By reference to Figs. 2 and 6, it will be seen that the contacting faces of the interlocking stiles A A are arranged diagonall and each face consists of a straight midd e portion A and curved side portions A and A, and the said straight middle portion A of the grooves A A extending throughout the length of the stiles and arranged for the reception of a packing, preferably in the form of rubber tubing E, through which passes a core E of metal, wood or other material, and screwed or otherwise secured to one of the stiles, as shown in Fig. 6, to the stile A Thus when the sashes A, A are closed the outer portion of the rubber tubing E passes into the groove A of the stile A (see Fig. 2), and hence a dust proof and air tight joint is ha'cl between the interlocking stiles A A".

Similar packings F, F, F and F are arranged between the sash frames and the window frame B, at the bottom, sides and top, but this construction is fully shown and described in the Letters Patent of the United States referred to above, so that further description of the same is not deemed necessary. The sashes A and A are provided with fixed cross bars G, G and intermediate muntin frame bars H, H, and the upper portion of the window is provided with a fixed muntin sash I having intermediate bars I, I I in vertical alinelnent with the interlocking spectively, thus producing a highly ornamental window having the a pearance of a fixed muntin frame sash, but 7 eing in reality provided with swing sashes.

Although l have shown the parts of the sash frames and window frame of tubular metal, it is evident that I do not limit my: self to the use of metal, as wood or other ma terials may be substituted.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

A window comprising a mullionless window frame, sashes mounted to swing in the said frame and having their adjacent stiles interlocking when the sashes are closed, the contact face of each interlocking stile having a straight middle portion and curved side portions, and a packing held in recesses: formed in the said straight middle portions.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

SIDNEY U. BARR.
